Families do not need separate kitchens. They need a shared dinner strategy that lets each athlete scale carbs, protein, and extras to fit the real demand.
A thrower and a distance runner do not need the same plate
Distance athletes usually need more carbs around training and meets.
Power athletes often need more overall calories and steady protein.
Trying to make them eat identically usually under-fuels one of them.
Growth, puberty, and body size also change the answer
Two athletes the same age may still have very different energy needs.
Menstrual losses, growth spurts, and body mass all matter.
Parents should expect range, not symmetry.
Serve one meal with scalable pieces
Use a main carb, a protein, produce, and optional add-ons at dinner.
Let each athlete build a plate that fits the day they had.
This lowers household stress without forcing identical portions.
Keep sibling comparison out of the kitchen
Comments like 'why do you need more than your brother?' are harmful fast.
Different needs are normal, not suspicious.
Performance support works better than fairness language here.
